Background and Objectives Endoscopes are recently being used to manage various middleear surgeries including ossiculoplasty. Here, we investigated hearing results of endoscopicossiculoplasty and surgeon’ learning curve in gaining endoscopic ossiculoplasty proficiency.
We compared the results with those of microscopic ossiculoplasty.
Subjects and Method We analyzed 48 patients of ossiculoplasties performed from 2010 to2020. Patients were divided into three groups: microscopic technique group (n=16); endoscopicearly phase group (n=16); endoscopic late phase group (n=16). Operation time and hearingresults including postoperative air-bone gap (ABG) and ABG closure were analyzed. Hearingoutcomes were considered “successful” when the postoperative ABG was less than 20 dB andconsidered “excellent” when ABG was less than 10 dB. The learning curve of the outcomeswere analyzed.
Results Both operation time and postoperative ABG showed decreasing tendency, but onlyoperation time showed statistical significance. The ratio of successful and excellent operationsimproved, but did not show statistical significance. Improvement in learning curve was notstatistically significant presumably due to the lack of patient numbers.
Conclusion Surgeon’s proficiency of endoscopic ossiculoplasty was correlated with the improvedclinical outcomes, and proficiently conducted endoscopic ossiculoplasty could be usedas a surgical technique comparable to microscopic ossiculoplasty.
